Description
Die Erfindung betrifft eine Meßvorrichtung für strömen de Medien in einer Rohrleitung, insbesondere für Treib stoffe und Gase.The invention relates to a measuring device for currents de Media in a pipeline, especially for blowing substances and gases.
Die übliche Abrechnung einer Lieferung von Treibstoff oder Gas erfolgt nach dem gelieferten Volumen. Bekann terweise tritt bei einer Temperaturerhöhung eine Volu menausdehnung ein, so daß zwischen dem berechneten Volumen und dem tatsächlich gelieferten Volumen eine Differenz vorhanden ist. Da in einer Vielzahl von Fällen das gelieferte Medium eine höhere Temperatur aufweist als der Abrechnung zugrunde gelegt wird, ergibt sich eine Schwundmenge, die sich kostenmäßig negativ auswirkt.The usual settlement of a delivery of fuel or gas is based on the volume supplied. Known Volu occurs when the temperature rises expansion, so that between the calculated Volume and the volume actually delivered Difference is present. Because in a variety of If the medium supplied is at a higher temperature than is used as the basis for billing, there is a shrinkage amount, which is cost has a negative impact.
Der Erfindung liegt die Aufgabe zugrunde, die Abrech nung für das gelieferte Medium exakt den tatsächlich vorhandenen Parametern anzupassen und auszuschließen, daß Schwundmengen in die Abrechnung einbezogen werden. The invention has for its object the billing for the medium supplied exactly the actual one adjust and exclude existing parameters, that shrinkage quantities are included in the settlement.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zur fortlaufenden Messung der Temperatur und/oder der Dichte des Mediums eine Meßsonde in Form eines Tempera turfühlers oder einer Ultraschallsonde in das strömende Medium reichend angeordnet ist, wobei die Meßsonde in einem in die Wandung der Rohrleitung angeordneten Aufnah meelement gelagert ist. Die Meßsonde kann von einer elastischen Umhüllung umgeben sein.This object is achieved in that for continuous measurement of the temperature and / or the Density of the medium a measuring probe in the form of a tempera sensor or an ultrasonic probe into the flowing Medium is arranged, the measuring probe in a receptacle arranged in the wall of the pipeline meelement is stored. The measuring probe can be of a be surrounded by elastic sheathing.
In Ausgestaltung der Erfindung ist das Aufnahmeelement zweigeteilt ausgebildet. Das Aufnahmeelement kann hierbei aus einer in die Rohrwandung einschraubbaren Schraub aufnahme und einem als Gegenstück dazu ausgebildeten Einschraubelement gebildet sein. Zweckmäßigerweise ist zwischen der Schraubaufnahme und dem Einschraubelement eine Dichtung in Form eines O-Ringes angeordnet.In an embodiment of the invention is the receiving element trained in two parts. The receiving element can from a screw that can be screwed into the pipe wall recording and a trained counterpart to it Screw-in element be formed. It is expedient between the screw receptacle and the screw-in element a seal arranged in the form of an O-ring.
Bei einer bevorzugten Ausführungsform weist die Schraub aufnahme U-förmigen Querschnitt auf, wobei der Steg teil weise nach innen aus der Rohrwandung herausragt und auf der Außenseite des Stegs ein umlaufender Kragarm angeord net ist, der an der Außenseite der Rohrwandung anliegt. Vorteilhafterweise ist auf der Außenseite der Schraubauf nahme zwischen dem Kragarm und der äußeren Begrenzung des Steges ein Außengewinde angeordnet und der Flansch mit einem Innengewinde versehen.In a preferred embodiment, the screw Recording U-shaped cross-section, with the web part protrudes inwards from the pipe wall and on a circumferential cantilever is arranged on the outside of the web net, which lies on the outside of the tube wall. The screw is advantageously on the outside between the cantilever and the outer boundary of the An external thread is arranged and the flange with provided with an internal thread.
Nach einem weiteren Merkmal der Erfindung weist das Einschraubelement T-förmigen Querschnitt auf, wobei der Steg mit einem Außengewinde versehen ist, das in das Innengewinde der Schraubaufnahme einschraubbar ist. According to a further feature of the invention, this Screw-in element T-shaped cross section, the Bridge is provided with an external thread that in the Internal thread of the screw receptacle can be screwed in.
Zweckmäßigerweise liegt das Einschraubelement mit der Innenseite des Flansches auf der Stirnseite des Flansches der Schraubaufnahme an.The screw-in element is expediently located with the Inside of the flange on the face of the flange the screw holder.
Nach einer weiteren Ausbildung der Erfindung ist die Meßsonde über eine Datenleitung an ein Auswertungsgerät angeschlossen. Besonders vorteilhaft ist die Anordnung der Meßvorrichtung in einem in die Rohrleitung ein- bzw. aufschraubbaren Adapter, wobei die Meßeinrichtung geeicht und/oder in einem verschließbaren Gehäuse gelagert sein kann.According to a further embodiment of the invention Measuring probe via a data line to an evaluation device connected. The arrangement is particularly advantageous the measuring device in one into the pipeline or screw-on adapter, whereby the measuring device is calibrated and / or be stored in a lockable housing can.
Durch die Erfindung ist die Möglichkeit gegeben, exakt die tatsächlich gelieferte Menge des Mediums der Abrech nung zugrunde zu legen.The invention provides the possibility of being exact the actually delivered amount of the medium of billing basis.
Ein Ausführungsbeispiel der Erfindung ist in der Zeich nung dargestellt und wird nachfolgend näher beschrieben. Es zeigen:An embodiment of the invention is in the drawing shown and will be described in more detail below. Show it:
Fig. 1 einen Querschnitt durch eine Meßvorrichtung nach Linie I-I der Fig. 2 und Fig. 1 shows a cross section through a measuring device according to line II of Fig. 2 and
Fig. 2 einen Längsschnitt durch eine Meßvorrichtung. Fig. 2 shows a longitudinal section through a measuring device.
Eine Meßsonde 2 in Form eines Temperaturfühlers ist in einem in die Wandung 5 der Rohrleitung angeordneten Aufnahmeelement so gelagert, daß ein Teil in den Quer schnitt der Rohrleitung reicht und von dem durchfließen den Medium umspült werden kann. Hierdurch ist eine exakte Messung der jeweiligen Temperatur des fließenden Mediums möglich. Über eine Datenleitung 6 werden erfindungsgemäß die laufenden Meßwerte in ein Meßgerät übertragen, wobei diese Übertragung auch in vorgegebenen Abständen, z. B. im Abstand von 30 Sek., erfolgen kann. Über eine LCD-An zeige kann jederzeit die gemessene Temperatur abgelesen werden. Nach Beendigung des Betankungsvorgangs wird über das Meßgerät der rechnerische Schwund ermittelt. Bei vorhandenem Druckeranschluß kann ein Beleg mit den rele vanten Daten, z. B. gelieferte Menge, Liefertemparaturen und Schwundmenge, ausgedruckt werden.A measuring probe 2 in the form of a temperature sensor is mounted in a receptacle element arranged in the wall 5 of the pipeline in such a way that a part extends into the cross section of the pipeline and from which the medium can flow around. This enables an exact measurement of the respective temperature of the flowing medium. According to the invention, the current measured values are transmitted to a measuring device via a data line 6 , this transmission also at predetermined intervals, for. B. at intervals of 30 seconds. The measured temperature can be read off at any time via an LCD display. After the refueling process has ended, the calculated shrinkage is determined via the measuring device. If there is a printer connection, a receipt with the relevant data, e.g. B. quantity delivered, delivery repairs and shrinkage quantity can be printed out.
